This code might be useful for some, but I know it is not being useful
for me. I use e.g. dreamhost.com as my mail provider and I never have my
email domain name show up after the Received: by .....
See my Received headers for your message below.

On the other hand, it contains "for <sebastian at sspaeth.de>" stating the
intended email address explicitely. IMHO, we should use this before we
start some hand-wavy guessing.

Also, I have the "X-Original-To: sebastian at sspaeth.de" header. Is that
something that we could make use of before starting to guess?
